The correct solution is to put the wireless headset into pairing mode. Most wireless devices require being in a specific pairing mode to become discoverable by other Bluetooth-enabled devices. This mode is often activated by holding down a particular button or series of buttons on the device until an LED indicator flashes in a specific pattern. Activation of pairing mode is typically detailed in the device’s user manual. Turning on Bluetooth on the laptop would not resolve the issue if the headset is not in pairing mode. Replacing the headset would be an unnecessary step if it simply has not been put into the correct mode for pairing. Restarting the router would not affect Bluetooth pairing, as Bluetooth is a direct device-to-device communication method.
